Specification of Letters Patent.

Patented July 6, 1909.

Application filed. December 29, 1908. Serial No. 469,822.

To all whom it may concern:

Be it known that I, CALVIN L. Srnnons, a citizen of the United States,and a resident oi Spokane, in the county of Spokane and State of Viashington, have invented a new and Improved. Grapple, oi which thefollowing is a full, clear, and exact description.

The invention relates to grapples, such as shown and described in theLetters Patent ol' the United States, No. 905,010, granted to meNovember 2-1, 1908.

The object of the present invention is to provide a new and improvedgrapple ior hoisting concrete blocks and other articles,

and having adjustable and reversible means to permit the use of thegrapple for hoisting small and large blocks, and for grappling a blockeither outside or inside. i I

A practical embodiment of the invention is represented in theaccompanying drawings forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in bothviews.

Figure 1 is a perspective view 01 the improvement as applied to aconcrete block having double air spaces; and Fig. 2 an enlarged end viewof the improvement as applied, the block being shown in cross section.

The grappling levers A, A of two pairs of said levers, are provided withadjustable and reversible grappling arms B, B adapted to be fastened tothe corresponding grappling levers by set screws C or other fasteningmeans. The free ends of the gra n'iline; arms B, B are provided withpoints D it or ongagcment with the block D, either at the inside, asshown in lull lines in Figs. 1 and 2, or at the outside of the block, asindicated in dotted lines in Fig. 2. The inner ends of the grapplinglevers A, A of the two pairs of said levers are pivoted on a handle E,and the outer ends of the grappling levers A, A of each pair arepivotally connected by toggle links F, F with the corresponding ends oia second handle G arranged a distance above the handle E. Stop pins Hextend. upwardly from the fulcrum ends of the grappling levers A, A, toprevent the toggle links F, F from opening too far in a downwarddirection, that is, to leave suflicient space between the handles G andE for the operator to conveniently take hold of either of the handleswhen hoisting the block D, as hereinafter more fully explained.

By rel'crence to the drawings it will be seen that the grappling leversA, A are pro vidcd with suitable guideways for the grappling arms B, Bto slide on, to permit of ad justing the said. grappling arms to blocksD oi diilerent sizes, and to allow of reversing the said grappling armsfor engagement with the inside or outside of the block D. Now when thegrappling arms B, B engage the inside of the block D, as shown in Figs.1 and 2-, then the handle 6- becomes the carrying handle and is engagedby the operator taking holdv of this handle G to carry the block Dabout, it being understood that the operator on lifting the handle (3*causes a closing or the toggle links F, F, thus swinging the grapplinglevers A, A upward and moving the points B B" of the grappling arms B, Bin firm contact with the inner walls of the block D. When it is desiredto release the block D alter the same is deposited on a suitablesupport, it is only necessary for the operator to take hold of thereleasing handle E with one of the lingers, to draw the carrying handleG toward. the releasing handle E, so that the pairs of grappling leversA, A are caused to open, thus disengaging the points B B from the innerwall of the block D.

When the grappling arms B, Bare arranged on the levers A, A forgrappling the out-side ol' the block D, as indicated in dotted lines inFig. 2, then the handle E becomes the carrying handle while the handleG- becomes the releasing handle, that is, the operator takes hold of thehandle E to carry the block about and uses the handle Gr for releasingthe bloclc alter the same has been taken to its destination. In thiscase the releasing handle G is drawn down toward the carrying handle Efor disengaging the points B, B from the outer wall of the block D.

From the foregoing it will be seen that by the arrangement described thegrapple can be readily used for engaging a block at the inside or at theoutside and for adapting the grapple to bloclts oi di'tl ercnt sizes.

Having thus described my invention, I claim. as new and desire to secureby Letters Patent:

1. A grapple comprising a pair of levers pivotally connected with eachother at their inner ends and carrying adjustable grappling arms forengagement with the article to be hoisted, a handle, and linksconnecting the other ends of the said levers with the said carryinghandle.

2. A grapple comprising a handle, two pairs of levers, each levercarrying an adjustable grappling arm, a pair of links connecting eachend of the said handle with a pair of the said levers, and a secondhandle, to each end of which a pair oi the said levers is pivoted.

3. A grapple comprising a pair of levers pivotally connected with eachother at their inner ends and carrying adjustable and reversiblegrappling arms for engagement with the article to be hoisted, a handle,and links connecting the other ends of the said levers with the saidcarrying handle.

4. A grapple comprising a handle, two pairs of levers, each levercarrying an adjustable grappling arm, a pair of links connecting eachend of the said. handle with a pair of the said levers, a second handle,to each end of I which a pair of the said levers is pivoted, and

stops for keeping the handles spaced apart. 5. A grapple comprisinggrappling levers I having reversible and adjustable grappling arms, ahandle on which the said levers are fulcrumed, a second handle, andlinks connecting the said levers with the said second handle, either ofthe said handles being the carrying handle while the other is thereleasing handle, according to the position of the grappling arms ontheir grappling levers. In testimony whereof I have signed my name tothis specification in the presence of two subscribing witnesses.
